| Abstract | Delineation and characterization of areas subject to periodical inundation remains a challenge in the study of Amazonian wetlands, considering the geographical complexity of these environments. Hess et al. (2003) performed the only existing wetland habitat map for the mainstem Amazon floodplain, using synthetic aperture radar images from the Japanese Earth Resources Satellite 1 (JERS-1). These authors have produced a wetlands mask product for the entire basin, which has been used extensively by researchers. Recent studies have shown evidence of geometric distortion and mapping inconsistencies in this product, resulting from the process of automatic delimitation. The present paper analyzes a procedure for revision and correction of the original mask product, identifying the main types of distortion and comparing area differences between original and edited products. The revision procedure was based on visual interpretation and manual digitization of the original mask product, based on three main image sources: the original JERS-1 high water mosaic, the Shuttle Radar Topography Mission global elevation dataset, and a mosaic of orthorectified LandsatTM + images from the GeoCover dataset. The use of two additional sources was invaluable to resolve ambiguities and inconsistencies in areas where JERS-1 images did not allow clear distinction of wetlands. Considering the first 40 1º x 1º grid cells edited to date, the results show that the difference in area between the original and corrected masks was of approximately 3500 km² (3% of the total corrected area). Grid cells with the largest variation had a decreasing trend in area, reaching up to 16%. Most grid cells, however, had up to 10% reduction over the originally mapped area, suggesting a slight overestimation of the wetlands by Hess et al. 2003 research. |
